modding z-2300 subwoofer amplifier help? (and what is the weird thingie?)

[erikb1971]

HI all

Iam taking apart my logitech z-2300 subwoofer so I can build it in a new cabinet integrated with the TV furniture. Now I thought: Would it be possible to modify the amp? Replace the big samxon caps? Or the small ones (close up added)? Or both? I have taken a picture of the board and tried to explain a bit what is what for as far as it is not visible on the pic. Any Ideas?

I would also like to know what the thing is that I labelled weird thingie. I have also posted a close up of it. Curious!

BTW Iam only using the z2300 for the subwoofer, my gainclone wichg iam finbishing this week is powering a set of Anthony Gallo Nucleus satelites.

Tnx! Erik

It is a bridge rectifier. I suggest you leave things alone, it's not a bad design and replacing things without really knowing what you are doing can result in issues that you never even dreamed of.

"weird thingie" is the bridge rectifier. It's got 4 diodes inside.

ooohhh ofcourse, makes sense, didn't think it would be that small! Tnx!

point taken... although it almost sounds tempting

If the unit is now only driving the sub rather than a 5.1 setup it will relieve the power supply of a lot of work so things should improve for free
